Pull up following revision(s) (requested by martin in ticket #1274):
        sys/arch/sparc64/sparc64/db_trace.c: revision 1.51
        sys/arch/sparc64/sparc64/db_trace.c: revision 1.52
        sys/arch/sparc64/sparc64/db_trace.c: revision 1.53
Relax test for valid stack frame address (now that we have multiple kernel
stacks since ... a long time). Just test for a valid kernel VA, using
the same test as for "pc".
Very close to a patch suggested by Tobias Ulmer in PR port-sparc64/54221.
Fix previous and use the original patch from PR port-sparc64/54221
instead (XXX should fix comments in param.h)
Add missing include to fix the crash(8) build, from Tobias Ulmer, PR port-sparc64/54221
